Application December 24, 1942, Serial No. 470,054

Claims. (Cl. 129-25) This application contains subject matter similar to that disclosed in my U. S. Letters Patent No. 2,323,393 dated July 6, 1943 and in my copending patent application Serial No. 453,189 filed August 1, 1942 and refers in particular to the binding blank or member revealed by said patent and patent application.

It is an object of the present invention to provide a binding blank or member for :loose leaves, which blank may be transformed into various shapes according to its application.

It is another object of the present invention to provide as a new article of manufacture, a bind-- ing assembly which may be readily secured to a support, such as a folder, and may simultaneously serve the purpose of holding in place the loose leaves to be enclosed by'said folder.

Still another object of the present invention is to provide a binding blank or' member which may include or incorporate, if desired, a strip fastener to be threaded through perforations of loose leaves for securing the latter on said binding member.

It is a further object of the present invention to provide a foldable, elongated binding blank, which may be scored lengthwise thereof orotherwise so prepared as to readily permit transformation of said blank into variousshapes for differentuse and application of said blank.

Yet, another object of this invention is to provide means forming part of or connectible with said foldable blank so as to facilitate the inclusion or incorporation'of a binder- .or fastener strip in theblank and to secure to the latter the tangs or ends of said fastener strip in looking position.

These and other objects and advantages of the invention will appear from the following disclosure thereof together w-ith theattached drawing which illustrates certain forms of embodiments thereof. These forms are shown for the purpose of illustrating the invention sincethe same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that .the invention is not limited. to the precise arrangement and organization of the .instrumentalities ,as herein shown and described.

Inthe drawing:

Fig.1' is a perspective view, showing the re.- verse side of .a three-part binding blank made in accordance with this invention and havin attachetl to its middle part a flexible fastener strip. v

Fig. 2 shows the transformation :and subsequent application of the binding blank of Fig. l to asupport.

Fig. 3 shows the binding blankof Fig. '1 transformed to a two-part binding assembly with .two ends of adjacent blank sections attached together, whereas the middle portions of said adjacent blank sections are in .open condition."

Fig. 4 shows the three-part binding blank of Fig. 1, transformed and with the middle portions of the joined adjacent blank sections connected together, the ends thereof being unattached.

Fig. 5 shows a fragmentary view of the transformed binding assembly of Fig. 4 with an end of the binder strip threaded through locking means consisting of an aperture and unattached ends of the transformed binding blank. I

Fig. '6- shows a perspective View of the binding blank in transformed condition and including a modified form of the locking means for the ends of the binder strip applied to said transformed binding blank.

' Fig. 7 shows a similar view as that of Fig. 6 with the locking means in modified form.

Referring to the attached drawing, there is shown in Fig. 1a binding blank 22 which may assume any desired shape and configuration and may include any means for attachment thereof to a support or carrier for'loose leaves and. the like.

blank 22 may be prepared with an adhesiv coating 22d entirely covering one surface of the blank 22; it being understood, however, that the adhesive coating may extend only partly over all or only over one or two sections of the blank.

Blank 22, as shown in its unfolded condition in Fig. 1 has, in this instance, three parts or sections 23, 24a, 24b of which section 23 forms the base section or flap. Fold lines 22a, 22b hingedly connect section 23 with section 24b and section 241) with section 24a, respectively. The sections 23, 24a and 241) may be provided with perforations (one .or two pairs) :29, 30; 29a, 30a; 3|, 32; 3la, 3211,33, 34; and 35, 36.

Disposed on the uppermost surface of said coating on the intermediate part or section 241) there is a flexible fastener strip a, preferably made of acetate material, having prongs or tangs 68, 69, which extend downwardly through perforations 29, 30 of said section .221).

One mode of transforming blank .22 of Fig. 1 is illustrated in Fig. 2. Blank section 24a has been folded over fold line 22a and .has been adhesively secured to adjacent or intermediate sec- Fig. 1 shows that the reverse side'of binding tion 241) in superposed position. Outer section or flap 23 has been adhered to support Ill by said adhesive coating 22d so that the joined sections 24b and 24a forming a binder strap can be swung about fold line 22b and relatively to outer section 23.

Thus a reinforced strap is obtained in which the fastener strip 65a is interposed between said joined sections which strip projects with its tangs or ends 68 and 69 through registering perforations 30 and 29 and 29a, 30a for any desired purpose.

It is quite evident that the prongs or tangs 68, 69 can be used for receiving and holding loose leaves which are correspondingly (not shown).

Fig. 3 shows fastener strip 65a placed between adjacent sections 24a and 24b; the ends of which perforated tions to be provided in registry therewith in the flap sections.

It is to be noted that the fastener strip can also be applied to the combined or joined binding strap sections from the outside instead of being positioned intermediate said sections, as aforesaid.

It is further to be observed that the fastener strip may be thus permanently or removably combined with the binding blank, as described and shown and the prongs or tangs of the fastener strip may also be permanently or removably secured in looking position according to the construction of the ends of the strap sections of the binding blank.

. It will thus be seen that there has been provided by this invention a binding assembly of the only being adhesively and firmly connected,

whereas a space 24c is provided between the middle portions of sections 240. and 24b. Thus fastener strip 65a can be easily inserted to project with its prongs 68, 69, for example, through registering perforations 30; 30a and 29, 29a as illustrated, to engage similarly perforated loose leaves etc.

Fig. 4 shows the fastener strip 65a fixedly held in position between and atithe middle portions of sections 24a and24b which are adhesively or otherwise, connected together at said middle portions, whereas the ends thereof are not united so as to allow manipulation of the prongs or ends 88, 69 with respect to the inner or outer perforations provided in said sections 24a, 2427. Thus the said'prongs may engage perforated loose leaves and then be held in locking position between said ends of said sections 24a, 24b either permanently or removablyorin any desired manner.

One form of locking position is shown in Fig.5 illustrating a fragmentary perspective view of the end of the transformed blank 22, the prong 69 passing through inner perforation 29 of intermediate section orpart 241), then through its outer perforation 32 to be finally held in looking position between the ends of sections 24a and 2412, as clearly seen in Fig. 5.

Fig. 6 shows a top plan view similar to that of Fig. 2. whereas prongs 68 and 69 of fastener strip 65a are threaded;through perforations 39, 29i and are being removably held in looking position'in slots H and 12 of the joined flap parts 24a and 241). a

A similar locking construction is shown in- Fig. 7, the fastener strip 65a being placed between sections 24a and 24?), which are then permanently secured together. The prongs 6H, 69 penetrating through perforations 29 and 353 are removably held in locked position when threaded through outer perforations 80 and 8| of the joined sections. These outer perforations are in out-of-alignment position with respect to inner foldable blank. either prior to or after being ap plied to a folder or support so as .to conformthe perforations of the loose'leaves' to the' perfor Base or flap 23 is not perforated,.

character described in which the various objects hereinabove set forth, together with many thoroughly practical advantages, are successfully achieved. The new binding assembly is mainly characterized by a paper blank, an adhesive coating on one surface of said blank, said blank having three sections forming a flap adapted for attachment with a support, the remaining sections being foldable in superposed position for being adhered with one another by said adhesive coating, and a fastener strip including prongs atits ends, at least one of said remaining sections having spaced perforations, at least a portion of said fastener strip being disposed between said remaining sections when in superposed position and with'said prongs projecting through said perforations of said one of said remaining sections to receive a. paper sheet thereon.
